Is it possible to create Notification Emails with HTML Elements?

I would like to create an HTML mail to include more visualization for report notifications. Is there a way to do it? I tried to include HTML code in the notification text field of scheduled reports, but it is interpreted as text in the final mail. Can i directly include the code and receive the mail in the HTML format with code interpreted?

I am not sure how this would increase the attack surface. I mean when the admin of the qualys interface inserts iframes etc. then something else is broken. But one could think about a small amount of allowed tags (e.g. allowing tables, enumerations). Then a MitM attack is as likely as it is with plain-text mails
